Q: How Do You Become a Rockhound?

A: Buy a large bag of marbles and carry it with you whenever you go looking for rocks. Every time you pick up a rock and put it in your pocket, take out one of the marbles from the bag and throw it over your left shoulder. Any time you see one of your marbles, pick it up along with the rock nearest to it--the rock goes in your pocket, the marble into the marble bag. When you have finally lost all of your marbles, you are a rockhound.
